1860 Empress Eugénie and Napoleon III by Andre Adolphe Eugene Disderi

Empress Eugénie and Napoleon III are dressed to go out in this photograph.

Disderi invented the carte de visite (cdv).

From Wikipedia; blotches and spots had to be removed from throughout the image with Photoshop.

Empress Eugénie wears a jacket contoured to the dress beneath instead of a paletot. She also wears a bonnet, headwear that was becoming passé. The dress may be the one shown in the preceding images - it appears to have five flounces, four of which can be seen in this image.
